MACHINE FOR MIXING MORTAR.

SPECIFICATION forming part of Letters Patent No. 232,150, dated September 14, 1880.

Application filed March 22, 1880. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL L. SHELLEN- BERGER, residing atDenison Gity,in the county of Grayson and State of Texas, have invented Improvements in Machines for Mixin g Mortar, 850., of which the following is a specification.

My invention consists in a cylinder composed of bars set into open heads and rotatin g beneath a hopper, apart of the circumference of the cylinder forming the bottom of the hopper, so that the material to be mixed rests upon the cylinder, and is rasped or grated off by the motion of the cylinder and received on the inside of the cylinder between the bars. That remaining between the bars will be carried around and forced inside by projecting bars upon a cylinder, so that the spaces between the bars will be cleared before entering the hopper, ready to receive another charge.

When the material is received inside the cylinder itis carried around by the rotary mo tion, and is turned OW'I and forced out at one end of the cylinder by coming in contact with a number of fixed spiral blades or scrapers attached to the fixed shaft upon which the cyl- I inder revolves.

My improvement consists in the combination of parts, as described in the claims.

In the drawings, Figure l is a section at am, Fig. 3. Fig. 2 is an end view. Fi 3 is a horizontal section at so 00, Fig. 1. Fig. 4 is an enlarged detail, part in section, showing the device for clearing the spaces of the cylinder. Fig. 5 is an enlarged detail section, showing the manner of securing the bars to the heads.

A is a frame. B is a hopper to contain the material to be mixed or ground, (which may be mortar or may be lire-clay or other clay for making bricks, tiles, or other things.)

0 is the cylinder projecting into the hopper, as shown, so that part of its circumference is in contact with the contents of the hopper. The cylinder has two open heads, a 0, cast in the form of a wheel, and turning on a fixed shaft, D.

The heads are cast with holes 0 extending through the rim to receive the ends of the bars 0", forming the circumference of the cylinder. These bars are fixed in by riveting their ends, as shown in Fig. 5.

The part of the cylinder below the bottom of the hopper is inclosed in a case, E, conforming to the shape of the cylinder.

F is the clearing-wheel, which carries bars f, entering the spaces between the bars 0 and forcing the material inward from said spaces. The bars 0 and f act as cogs to drive the wheel F from the cylinder 0; but ordinary gearing may be provided in addition.

The rim of the wheel F is cast with projecting studs j", which pass through the bars f, and are riveted, as shown in Fig. 4.

When the material is forced inward by the cleaning-bars fit is caught by the inclined scrapers or blades G, which are attached to the fixed shaft 1), and whose outer edges are just out of contact with the inner sides of the bars 0 so as to prevent the accumulation of the mortar (or other material) upon them.

The blades or scrapers G are placed in a spiral series, and are so inclined that by the rotation of the cylinder they convey the material to one end of the cylinder, where it is discharged.

One of the cylinder-heads--i. 6., c-is cast with a spur-wheel, H, upon it, which engages with a spur-pinion, I, on the driving-shaft.

K is a pipe to supply water to the material just above the place where the clearing-bars enter the spaces between the bars a".

L is an edge or knife clearing the outside of the cylinder (J as it leaves the hopper.

The direction of rotation of the cylinder is indicated by an arrow.

I claim as my invention 1. The combination of the barred cylinder G, rotating partly within the hopper B, with the spiral scrapers or blades Gr, operating as set forth.

2. The mixing-machine composed of a hopper, B, barred cylinder O, clearingwheel F, and spiral series of scrapers or blades, arranged and operating substantially as set forth.

3. Thecombination, in a mixing-machine, of the hopper B, cylinder 0, cylinder-casing E, clearing-wheel F, and series of blades G, all arranged substantially as set forth.
